From most energy efficient to least energy efficient:

LED bulbs (relativly new)

Fluorescent bulbs (normal "energy savings" bulbs)

Halogen (used for high intensity lighting)

Incandescent bulbs (regular bulbs)

Energy efficient light bulbs are bulbs that convert a higher percentage of electical power into light. All bulbs also create waste heat, where energy is radiated as infrared. The less efficient bulbs tend to be "hotter" because of the amount of power "wasted" this way.

Why are fluorescent light bulbs more energy efficient then halogen lamps?

they are more energy efficient cause they have less electricity


Are light bulbs really efficient?

Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity


What advantages do LEDS have over light bulbs?

LED light bulbs are energy efficient, environment friendly, and provide huge electricity savings.


Why do people say that ordinary light bulbs aren't energy saving?

No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs.


What does light bulbs do to the environment?

old fashioned light bulbs did nothing to the environment but the new energy efficient bulbs contain mercury which is bad for anything that comes in contact with it.


Do small watt bulbs save a lot of electricity?

Not always. They can, but using energy-efficient light bulbs is the best guarentee to be able to save energy, and still have plenty of energy and light produced.

Are traditional light bulbs wasteful?

Yes. Conventional (filement based) light bulbs are very inefficient converters of electrical energy to light - around 2% efficiency. So compared with "low energy" bulbs, which are around 8% efficient, they are wasteful.


Why are LED bulbs considered to be better at saving energy than compact fluorescent ones?

LED bulbs, or Light Emitting Diode bulbs are far more efficient at turning energy into light than fluorescent bulbs. They are the most energy efficient bulbs available today and last much longer than any other bulbs. Although very expensive, the price is expected to come down over time.


Fluorescent light bulbs are considered more efficient because they they?

Lose less energy as heat.
